Spare N15 domes are available from South Eastern Finecast.

....but it's probably too late for you now!

Thanks for that tip, Ivan. I didn't think of SEF.

If I can get hold of one of those that will save me a good deal of filing, filling and fettling.

Next stop: South Eastern Finecast's website!

Cheers.

Jeff.

Adding a couple more pics of progress. I have tidied up the dome shape a little, although it is still a bit crude at the moment. I'll post a new entry when there is more obvious improvement.

Hmmm....push your existing dome into some plasticine, remove locomotive, then 'cast' a new one from Milliput? But Horsetan has the best idea...SEF!

Yes, I'll be phoning SEF later this week. With the 11 hour time difference plus working full-time it makes things a little awkward. I won't be doing it tonight as I'm off to see Yes playing in St Kilda.  

The diameter is a little small, the top is too rounded, it's a little lopsided, and the base is still a little rough and crude, but it is starting to look like an N15 dome ... sort of. I have painted it roughly as that makes any faults more obvious than trying to detect them on the stark white of the Milliput.



Edit: addendum: I have now phoned up South Eastern Finecast, who were extremely helpful and are able to supply me with a cast white metal dome from one of their kits. That means I probably won't do anything more on Sir Lamiel until that arrives.
